Abstract (en)

A signal transmitted from the transmitting end to the receiving end intermittently includes a particular symbol having a predetermined particular patter in addition to a symbol including data to be transmitted. At the receiving end, the variation in the receiving level and/or the variation in the frequency band of a received signal are detected and corrected on the basis of the received particular symbol. Since the particular symbol has a particular pattern, the variation in the level and/or the variation in the frequency band of the received signal. Consequently, the variation in the receiving level and/or the variation in the frequency band of the received signal can be accurately detected from the particular symbol and consequently high-precision correction can be made.
